Start android application without activity
I've an application which aims to run only as a service (no interface, just run in background). I have no activity mentioned in my AndroidManifest.xml but put a receiver to start the application at phone start.
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >
<service
android:enabled="true"
android:name=".MyAppService">
<intent-filter>
<action
android:name = "me.myapp.MyAppService">
</action>
</intent-filter>
</service>
<receiver
android:enabled="true"
android:name=".BootReceiver">
<intent-filter>
<action android:name = "android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
The problem is that as I'm developing (using Eclipse) the application, I need to test my changes often. When I run the application (with my phone connected in debug mode), I've got a message like
[2011-12-14 00:18:40 - MyApp] Android Launch!
[2011-12-14 00:18:40 - MyApp] adb is running normally.
[2011-12-14 00:18:40 - MyApp] No Launcher activity found!
[2011-12-14 00:18:40 - MyApp] The launch will only sync the application package on the device!
[2011-12-14 00:18:40 - MyApp] Performing sync
How can I start the application at run, without having to restart it every time ?
Edit this is not possible anymore for Android 3.1 or above. Source
Solution 1:
Apart from the two options mentioned by EboMike: You can always send the BOOT_COMPLETED
broadcast via the command line instead of rebooting your phone.
Use
adb shell am broadcast -a android.intent.action.BOOT_COMPLETED
This will result in a situation like after an actual reboot, and will also trigger any 3rd party apps boot receivers. After typing it once in a terminal you can usually repeat it simply by pressing the up-arrow key followed by return on most operating systems. Or you can include it in a script thats triggered after reinstalling your app.
If you want to limit the broadcast to your app only, you can also specify a component:
adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -n your.app.packagename/.YourReceiverClassName
This sends the reboot broadcast only to your receiver. All other apps are not called.
Solution 2:
Option 1: Add a dummy activity that will start your service. Remove it before shipping.
Option 2: Create a second test application that starts your service.
